IMPROVEMENT IN IGNITIBLE COMPOUNDS FOR FRICTION-MATCHE$.

Specification forming part of Letters Patent No. 2,494, dated March 18, 1842 To all whom it nay concern:

Be itkuown that I, STEPHEN BLAISDELL, of Brunswick, in ,the county of Cumberland and State of Maine, have'luvented a new and useful IlilpI'OVClllQllh in the 'll/Ianu'iactureot' Jatch'es for the Instantaneous Production of Light by Friction, which is described as follows: r v

Prepare the pieces of wood f'orthe matches by sawing or otherwise, and dip them in sulphur in the usual manner. Then prepare a composition in the following manner: Take one-fourth of a pound of glue or other viseid substance and dissolveit in boiling water. To

this add three-fourths of apound of sulphur or brimstone and simmer them together over a slowflre, stirring the composition until thoroughly mixed. Then remove it from the fire, and when at a temperature of about 100 or 120 .Fahrenheit add three ouncesof phosphorus, and incorporate this thoroughly with the otheringredieuts bystirring. Letthe composition cool to about 100 of heat, which will be abohtthe light degree for dipping the matches, at which temperature it should be kept by placing the vessel in hot water to prevent ignition during the-process of dipping. Then dip the matchesin the aforesaid composition and lay them aside to dry. When thoroughly dry cover the co nposition on the matches with a coat of 'eopal or other varnish to exeludethe air and prevent accidental ignition. After the varnish is dry 'inclose each block of matches in a paperaud pack them in packages of about thirty-six blocks each.

I am aware that sulphur and phosphorus. have been united in the composition of the like bottle formerly in use, but were not combined by means ofa glutinous substance, so as to allowof the com pound heiugadapted to the manufeature of friction-matches without the danger of ignition, as in-my inveution,'to which purpose the mixture of sulphurand phosphorus in the fire-bottle is not applicable, as the match introduced into this compound took fire without the use of friction or bein gwit-hdrawn from the bottle. An alkali in any required proportion may be used to dissolution of the sulphur; therefore What I claim as .my invention, and desire to secure by Letters Patent, is-

The manufacture of friction-matches bydip fping. the matches into a compound of sulphur and phosphorus formed into 'apaste or fluid by means of glue or any other glutinous or vis- I cid substance, as herein set forth..
